Study finds no benefit of early IABP use in cardiogenic shock patients

Compared with standard medical care, early use of a temporary intra-aortic balloon pump (IABP) to support heart function in patients who were critically ill with cardiogenic shock caused by heart failure did not improve 60-day survival or enable more patients to successfully transition to long-term treatment, according to featured clinical research presented at the American College of Cardiology's Annual Scientific Session (ACC.25) and simultaneously published in JACC

Pulse oximeter accuracy varies across skin pigment groups

The differences, or bias, between estimates of blood oxygen saturation levels as measured with pulse oximeters compared to the gold-standard method of measuring oxygen saturation in arterial blood varied significantly between patients with darkly pigmented skin compared to lighter skin pigment, according to research presented at the American College of Cardiology's Annual Scientific Session.

Gasdermin D found to play a crucial role in heart arrhythmias

Atrial fibrillation (AF) is a common form of heart arrhythmia, a serious condition in which the heart beats so fast that its upper chambers, the atria, quiver. This irregular heartbeat can increase the risk of severe conditions, including heart failure, dementia and stroke.

Novel insights into tumor microenvironment and gastric cancer therapy

A team of Singapore scientists has made a significant discovery in understanding stomach cancer, a disease that remains one of the deadliest cancers worldwide. By using advanced mapping technologies, they created a detailed "atlas" of stomach tumors, revealing hidden patterns in how cancer cells behave, evolve and interact with their environment. These insights could lead to more precise, targeted treatments that improve survival rates and reduce side effects.
